wireless local area network (WLAN)

A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio), and usually providing a connection through an access point to the wider internet. This gives users the mobility to move around within a local coverage area and still be connected to the network. Most modern WLANs are based on IEEE 802.11 standards, marketed under the Wi-Fi brand name.

Can you totally ban a PC from the local network?

I was wondering whether it is possible to ban a PC from LAN or WLAN totally or not? I know that banning according to MAC address is useless, as it can be altered. P.S: assume that no credentials are required to connect the LAN/WLAN.
